In Mr. Joey Latino’s Biology I class on Friday, the subject matter was genetics and problems associated with the interaction of multiple alleles on sex-linked traits such as color-blindness, baldness, and hemophilia. These freshmen and sophomores are quick to grasp the significance of Coach Latino’s lecture and go straight to the bottom line — they want to know if in 10 years they will be bald like Dad or Uncle Fred. For some of these teenagers, just thinking about their hair falling out sets off waves of panic, helplessness, dread, and despair — frenetic genetics.
